Only false and nil are false. Even "" is true. Tables can have both numeric and string entries. The two don't overlap. t [1] is distinct from t ["1"]. Uninitialized variables and nonexistent fields in tables are nil. or and and both have shortcut evaluation. = is assignment, == is equality comparison. not is boolean negation, but ~= is ...
Lua patterns deliberately lack the most complex regular expression constructs (to avoid bloating the Lua code base), where many other computer languages or libraries use a more complete set. Lua patterns are not even a subset of regular expressions, as there are also discrepancies, like Lua using the escape character % instead of \, , and ...
In science, a null result is a result without the expected content: that is, the proposed result is absent. [1] It is an experimental outcome which does not show an otherwise expected effect.
The consistent application by statisticians of Neyman and Pearson's convention of representing "the hypothesis to be tested" (or "the hypothesis to be nullified") with the expression H 0 has led to circumstances where many understand the term "the null hypothesis" as meaning "the nil hypothesis" – a statement that the results in question have ...
Lua version 5.3.4 is implemented in approximately 24,000 lines of C code. [3] [4] Like most CPUs, and unlike most virtual machines (which are stack-based), the Lua VM is register-based, and therefore more closely resembles most hardware design. The register architecture both avoids excessive copying of values, and reduces the total number of ...
This is the lua-mock library, used to create mock objects for use in unit testing. URL: https://henry4k.github.io/lua-mock/ Author: Henry Kielmann; Licence: Public domain; See the lua-mock documentation page for documentation.
This module includes a number of set operations for Lua tables. It currently has union, intersection and complement functions for both key/value pairs and for values only. . It is a meta-module, meant to be called from other Lua modules, and should not be called directly from #invo
